To all role/curt it "mi-t7, conocrrw Be it known that l, ETTILLIAM hi. Annnnson, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented it new and useful of which the following is a, full, clear, and exact description, reference being lied to the accompanying drawings, forming port of this specification, in which.--

lily in vention relates to improvement in leers for annealing glassware; sncl consists in devices by means of which currents of drafts oi sir are prevented lroni entering the leer and by means of Wllh'ill ljlifi glassware may be removed from the leer without nermitting the entrance of cold sir. i A

' I will now describe my invention, so that others skilled in the art may manufacture and use the some. i

In the drawings, 2 represents the leer, hey-- ing side walls 3 and roof 4. At the front end of the leer-ere the lines by means of which the leer is hosted. This leer may be of any desired form. At the front end of the leer is a closed entrance 6, having a suitable top or cover 7 At the inner end of this entrance 6 is adoor 8, secured to the outer ends of the srms 9, which arms at their other ends are pivoted, preferably, to the side wellsof the leer. The arms 9 may he so raised and low ererl us to move the door 7 upwardly on the ore of a circle by means of the sliding rod 19, which is operated the lever .11, situate outside the leer. .lDSlLlG of the entrance 6 and pivoted to the own 10 a lever 12, the other end or which is pivotecl to one of the firms l) in sui i manner that by the IllOVumerit the .(l 10 inwsrrlly the arm 12 is brought to 9. vertical position, thus lifting the arms 9 elevating; the door '7 suliiciently to allow the entrance of the pen containing the were to'he annealed.

any tllGl-lb during the charging operation. At the other or rear end of the leer is s. longitude nslly-niovehle cover or casing 14, which may he lormerl of metal, and it is closed. at the sides and top, open at the bottom and. inner end, and. provided with s verticsllyqnovsble door 15 at the end outside of the leer. The sides of this using i i are arranged to extend. downwardly to inclose the glassware in the pans 16, which pens beer on wheels 1 soul slide on tracks 18 on the licor of the leer. This cover or casing l t supported by the shesves 20, which sheaves are mounted be tween the side of the cover and e bracket 2L? and are arranged to run on the track I l which extends longitudinally in a recess in the side walls of the leer.

in Fig. 5 l show a modified form, in which the track 2 instead of being arranged in. a. recess in the side wells extends outwardly from the wall end it recess is formed in the sides of the casing 14. This modification is applicable to leers which have not heed. syiecislly built with reference to the use of my invention and in which recesses have not been formed in the side walls of the leer. Thecesing 14 is adapted to be drown out and pushed back in the rear end of the leer, and it is further guided bythe guide-rollers 26, which we mounted on suitshle journals extencling from the sirle walls of the leer end are edepted to prevent the lifting of the casing during the lon itudinsl movomcntci the some.

'l he operation is as follows: The pen for containing the glassware is lI)1OL1lll) into the inclossd entrance 6, where it is sl owed to re-' main during the time thepen is being filled. As this entrance is in the hottest portion of the leer, the glass is heated preparatory to its entrance into the inner portion of the leer. After the pen has been filled the door 7 is lifterl sulilcientl to enzible the pen to be pulled through the leer and then closed to prevent. the admission of sir. As the" loaded. pan reaches the other and cooler end of the leer it passes under the casing 14. This casing,

the door 15 being closed, together with the pan 16, is drawn, outwardly until the pan is outside of the leer, about half or a portion of the casing remifining within the leer. The

door 15 is then elevated sufficiently to clear mg I - It will beapparent from the foregoing descrip- .i1iclose the glass, and
